Thanks, a very helpful description on navigation marks (not too
internal as the user sees them and utilises them, as part of the GUI).
However, I am finding them inconsistent on my conversion of Calibre Quick Start Guide from EPUB to MOBI.
They are nearly all generated except 3:
- Common Tasks
- Task 2: Conversion
- Task 4: Interacting with e-book readers
These seem to correspond to only Headers which contain lower-level Headers. Coincidentally, the unreplaced TOC at beginning of book gains an extra BLANK same-level Header below these 3 anomalies.
Is this a bug?
I am also puzzled why the converted format book loses all the <h?> heading elements . Surely these are still needed?
Also, is there any way to retain the Font sizes and line breaks in chapter headings of the original? The Fonts always seem to get bigger and it seems to add a line break between CHAPTER n and the title below. I tried
Disable Font Rescaling in Look & Feel.
Sorry, I'm new to this and just a bit perplexed.
